20th Ave. & Harlan St.
Edgewater, CO
-

BACKGROUND
To address multimodal safety, mobility, and vehicular performance, the city of Edgewater retained MTJ to evaluate the feasibility of a compact-style roundabout at this commercial, highly constrained intersection.
-
SUMMARY
Alternative concepts addressed these key issues:
-Minimize/avoid undesirable ROW impacts to surrounding properties
-Ensure compatibility with existing and/or proposed roadway cross sections to include ped and bike design features – cycle track and on-street bike facilities
Accommodate necessary design vehicles:
-Large trucks/freight
-Transit and school buses
-Emergency response/fire trucks
Two alternatives were developed to evaluate optimal size/shape and fit with acceptable impacts. The optimal design was a non-circular 107’ x 95’ ICD compact-style roundabout. The compact-style design allows the central island to retain landscape features that will promote visual conspicuity for this application.
